It looks like quite illogical for me then ... /proc/cpuinfo only reports what the cpu reports. The 'ht' flag means not HyperThreading per se. It means it listens to the "rep; nop" sequence for example. Also all Hyperthreading capable cpus have this flag set, but that is a one way relationship. Esp since this needs more support than just the cpu.
